I am receiving this error after logging into the Enterprise Manager: The transaction log for database 'Enterprise_Mgr' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases. The database 'Enterprise_Mgr' is on Microsoft SQL Server.
This error is generated by Microsoft SQL Server when the database logs/files have become full and no data can be updated within the database.
The document below from MSDN explains what is happening here.
Enterprise Manager 12.8, 12.9
Microsoft SQL database
Please provide the error to the MSSQL DBA so they can clean up the transaction logs for the database. After they have been cleaned, restart the JBoss service.
